The LCM of 801,518,189,810 is 18671310.
Find LCM of 801,518,189,810 with Prime Factorization
| 2 | 801, 518, 189, 810 |
| 3 | 801, 259, 189, 405 |
| 3 | 267, 259, 63, 135 |
| 3 | 89, 259, 21, 45 |
| 7 | 89, 259, 7, 15 |
| 89, 37, 1, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 89 x 37 x 1 x 15 = 18671310
Therefore, the lowest common multiple of 801,518,189,810 is 18671310.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
801 x 518 x 189 x 810 = 63519796620
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
801 : 1, 3, 9, 89, 267, 801
518 : 1, 2, 7, 14, 37, 74, 259, 518
189 : 1, 3, 7, 9, 21, 27, 63, 189
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 801,518,189,810, is 1.
Now, the common factors can be found like this.
801:3x 3x 89
518:2x 7x 37
189:3x 3x 3x 7
810:2x 3x 3x 3x 3x 5
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 3x 3x 7 = 3402
Therefore, the value for common factors is 3402.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 63519796620/(1x3402)
LCM = 63519796620/3402
LCM = 18671310
Thus, we can understand that the LCM of 801,518,189,810 is 18671310.
